Как исправить «Не удалось найти файл набора инструментов» «CMake Ошибка: CMAKE_C_COMPILER не установлен, после EnableLanguage» cmake libjpeg-turbo.so?

Я работаю над созданием файлов libjpeg-turbo.so для разных архитектур ЦП.

Если я выполняю приведенный ниже cmake в своей папке сборки, я получаю эту ошибку, даже несмотря на то, что файл набора инструментов присутствует в этом пути: 

$ cmake -G"Unix Makefiles" \
      -DANDROID_ABI=arm64-v8a \
      -DANDROID_ARM_MODE=arm \
      -DANDROID_PLATFORM=android-${21} \
      -DANDROID_TOOLCHAIN=${gcc} \
      -DCMAKE_ASM_FLAGS="--target=aarch64-linux-android${21}" \
      -DCMAKE_TOOLCHAIN_FILE=$/home/ingrid/Android/android-ndk-r16b/build/cmake/android.toolchain.cmake \
       /home/ingrid/Ingrid/NeoReader/libjpeg-turbo-master/

Выход: 

CMake Error at /usr/share/cmake-3.5/Modules/CMakeDetermineSystem.cmake:104 (message):
  Could not find toolchain file:
  $/home/ingrid/Android/android-ndk-r16b/build/cmake/android.toolchain.cmake
Call Stack (most recent call first):
  CMakeLists.txt:7 (project)


CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

Однако, если я удаляю -DANDROID_TOOLCHAIN=${gcc} \ и -DCMAKE_TOOLCHAIN_FILE=$/home/ingrid/Android/android-ndk-r16b/build/cmake/android.toolchain.cmake \, тогда я могу сгенерировать файл .so, но он генерирует x86_64, а не arm64_v8a. Ниже приведен cmake и вывод для него: 

$ cmake -G"Unix Makefiles" \
      -DANDROID_ABI=arm64-v8a \
      -DANDROID_ARM_MODE=arm \
      -DANDROID_PLATFORM=android-${21} \
      -DCMAKE_ASM_FLAGS="--target=aarch64-linux-android${21}" \
       /home/ingrid/Ingrid/NeoReader/libjpeg-turbo-master/

Не могли бы вы сообщить мне, как устранить эту ошибку в цепочке инструментов, чтобы я мог сгенерировать файл libjpeg-turbo.so для архитектуры arm64-v8a?

Спасибо.
